Zalman Mordecai Klionsky had three sons with his first wife: Shimon, Mark, and Barnet. He also had a daughter who married Mr. Fishkin.

Zalman's second wife was Mrs. Flaksin, a widow who had at least two children: Israel and Dobke. The children took the name Klionsky.

Israel and Dobke were stepsiblings of Shimon, Mark, Barnet, and Mrs. Fishkin. However, there is a genetic relationship between Israel's descendants and those of both Barnet and Shimon due to the relationship between their wives.
